PROC_FIND(9)           NetBSD Kernel Developer's Manual           PROC_FIND(9)


NAME

     proc_find, pgrp_find -- find process or process group


SYNOPSIS

     #include <sys/proc.h>

     struct proc *
     proc_find(pid_t pid);

     struct pgrp *
     pgrp_find(pid_t pgid);

     extern kmutex_t *proc_lock;


DESCRIPTION

     The proc_find() and pgrp_find() functions retrieve process and process
     group structures from process ID pid and process group ID pgid.  Both
     functions must be called by holding a mutex(9) on proc_lock.


RETURN VALUES

     Upon successful completion, the described functions return a pointer to
     either struct proc or struct pgrp.  Otherwise, if the requested ID was
     not found, NULL is returned.
